Lymphocyte migration is commenced at the focal tissue and monocytes are also activated resulting in several immune responses to tumour cells at the focal tissue. The clinical efficacy of Gefitinib therapy may be brought by the reduction in the angiogenesis via blockade of EGFR and thus causing tumour necrosis.
